Darkspore

Darkspore was a video game that borrowed creature editing technology from Spore. It was described as "a fast-paced, science fiction action-role-playing game in which the player battled across alien worlds to save the galaxy from the mutated forces of Darkspore". In addition to the creature editor, the game featured a unique squad-based mechanic, various multiplayer options, and a player versus player arena. The game was released in North America on April 26, 2011 for Microsoft Windows, and in Europe on April 28, 2011.

EA seemingly has removed the store page of Darkspore from Steam, meaning any attempt to purchase it through Steam cannot be made. Those who have purchased it prior to the page's removal still have the game and can play it.

Plot

The Crogenitors were a race of scientists that established a massive empire encompassing an entire galaxy. Many of them performed secret experiments on the populations they oversaw. Being masters of genetic manipulation, they used their knowledge to create a personal army of genetic heroes, called Living Weapons. However, the discovery of an experimental amino acid that bonds to DNA changes everything. Capable of achieving a millennium in terms of evolution in a matter of hours, it has an immense potential to manipulate life to levels never achieved before.
